A310 Accupulser™ Pulse Generator

Train

in the train mode, the instrument provides all the functions of the pulse mode. in 
addition, the single pulse can be expanded to a train of pulses. the double pulse at 
the beginning of the event interval, remains as one pulse. the violation function is 

expanded to include overlapping 
train timing parameters.

the train mode may be 
demonstrated with the panel controls 
set as follows. the instrument should 
provide the waveform shown on 
Figure 3, at the isolAtor outPut 
connector. the other outputs behave 
in the same manner as in the above 
described pulse mode example.

Vary the two trAin GenerAtor dials and notice how the waveform timing follows 
the dial values. note that the outPut light is now brighter than in the pulse mode 
example. this is due to the fact that the train duration plus the double pulse are 
.5/8 of the event interval duration.
